    Can't tell whether A is in between B and E or not.
But, you know that BEC=BED
That should help you pin down AEC.
If A is between B and C
BEA+AEC=BEC
11x-12 + AEC = 4x+1
AEC = 13-7x
or, if B is between A and C,
AEC-AEB=BEC
AEC-11x+12 = 4x+1
AEC = 15x-13
Of course, A could be a lot of other places, too.

    You first have to find x. 
To find x, we need to add all the angles together to get 180°.
Since EC bisects BED, we know angle BEC and CED equal the same measure.
AEB + BEC + CED = 180°
(11x - 12) + (4x + 1) + (4x + 1) = 180°
Add like terms and solve
19x - 10 = 180
19x = 190
x = 10
Now, we substitute 'x' in AEB and BEC
AEB = 11x - 12
11 (10) - 12
AEB = 98
BEC = 4x + 1
4 (10) + 1
BEC = 41
98 + 41 = 139
AEC = 139
Hope this helps!
